BOXI 2pcs Rear Glass Window Lift Supports Struts Shocks Gas Struts Shocks Springs for Chevrolet Trailblazer 2002-2008/for GMC Envoy 2002-06/for Isuzu Ascender 2003-08 | Replaces 4575 SG330052 15050924

I installed these pistons on my 2004 GMC Envoy rear glass window. Boy, they have a lot of pressure, and my thinking is they have too much. The pistons not only holds the window up, but from when I press the release latch, it goes up automatically. All I can say is WOW.

As advertised, they fit my 2003 GMC Envoy XL and worked as good as when new. Good price and delivery. Easy to install.

Put the first one in with no issues. One second one, I couldn't get the top connector locking device to pop out. It just wanted to rotate. I took the old connector off the old lift and put it on the new one without any problems.

Fits right and seems to work great in holding the rear window up. Time will tell on the quality.

Worked much better than expected. Held up great. Comparable to oem.

They fit. Work great.

Worked perfectly. Instructions a little poor but once I got through that it only took 15 minutes to install. Window not hitting me anymore YEA!

Perfect fit. No longer need to hold old ones up with pair of vise grips clamped onto supports.
